COTTON-SEED LINTER.

Specification of Letters Patent.

Patented Mar. 14, 1916.-

Application filed December 16, 1914. Serial No. 877,544.

To all whom it may concern:

Be it known that I, HUGH E. SESSIONS, a citizen of the United States,residing at Columbia, Richland county, State of South Carolina, haveinvented certain new and useful Improvements in Cotton-Seed Linters, ofwhich the following is a specification.

This invention has reference to cotton seed linters of the typedisclosed in my prior Patents Nos. 962,722, June 28, 1910, and1,077,435, November A, 1913, and has particular reference to that partof the mechanism where the lint is conveyed to the condenser.

The purpose of the invention is to prevent the clogging of the lint inthe flue leading from the outlet of the linter to'the condenser and toevenly and properly distribute the material carried out through the flueon the surface of the condenser drum, whereby the product on the drumwill be of practically uniform character from one end to the other, notonly in thickness but in quality.

The novel features of the invention will be apparent from the followingdescription taken in connection with the accompanying drawings.

In the drawings, Figure 1 is a cross section of a linter having myinvention therein, and Fig. 2 is a partial plan view showing the form ofthe flue leading to the condenser. As shown in the drawings, the linteris of the type shown in my patents above mentioned including the outercasing 10, the saw cylinder 11, the brush cylinder 14 and the mote-board16. The rotation of the brush cylinder creates a current outwardly andupwardly at a considerable angle along the mote-board 16 and, asexplained in my prior patents, this current carries the lint which hasbeen separated from most of the motes and trash. The air currentcarrying the lint enters the flue leading from the outlet 17 to thecondenser 30 and that flue, as ordinarily made, is about twenty-fourinches long, but this length may, of course, vary. The outlet 17 extendspractically the entire length of the linter and is therefore ofsubstantially the same length as the brush cylinder. The end of the fluenext to the linter is of sufficient width to fit over the outlet 17 andits bottom wall 9.6 is preferably level with the outlet leading fromthat point at a slight upward angle to the condenser.

' The top wall 27 leads from above the outlet and the Walls 26 and 27are at an angle to each other flaring outwardly from the linter.

ing the end of the flue at the condenser of less width but of greaterheight than at the linter.v In linters as heretofore constructed therehas been a tendency of the particlesof lint to fall to the inside bottomwall 26 of the flue and to collect there to such an extent that theywould clog the flue and sometimes the lint would fall back into thelinter down over the mote-board.

, According to my present invention I have so arranged the parts thatthe current of air and lint passing up over the mote-board will bepartially deflected at the point where it leaves the linter and aportion of it will descend and strike the bottom inside wall I of theflue, thus preventing the collection of r the fine particles of lint atthat point and picking up any particles which may rest there. In thepresent construction the condenser is placed at a somewhat higher levelin reference to the linter than in my two prior patents above mentionedand the outvlet 17 is not made so large vertically. The

condenser may be raised three or four inches, but the invention is notlimited to the exact amount and the outlet 17 is closed a correspondingamount. Air passing upward at an angle over the mote-board strikes theshort board 29 at the upper edge of the 'outlet and because of the angleof travel of the air and the angle of this board, together with itsrelation to the lower wall 26 of the flue, a portion of the air will bedeflected downwardly against the lower wall, as above indicated.

In the constructions heretofore used, the

form of the flue leading to the condenser has tended to cause crosscurrents because of the inclinations of the walls and the result ofthese currents has been to carry light particles of trash and motes tothe center line of the perforated drum 31 of the condenser and thetrash'would therefore be collected at that point and deposited on thedrum, thus forming a streak down the center of the material wound on thedrum, which was of much lower grade than the balance of the material onthe drum. It had the appearance of a dirty streak which detracted verymuch fro'l th: value of the roll of material. I have discovered that bythe use of my arrangement above described the deflection of a portion ofthe air down against the bottom wall will distribute the material evenlyover the drum not only in thickness but in character and that there willnot be any material collection of trash and motes at any particularpoint, as distinguished from any other point. In other words, heinvention produces a product on the condenser of uniform qualitythroughout and thereby makes that product more valuable. The lint is ofthe same quality from one end of the condensing drum to the other.

Having thus described. the invention,

what is claimed and desiredto be secured by Letters Patent is:

1. In a device of the classdescribed, the combination with a cotton seedlinter having an outlet for air carrying lint, of a condenser, a flueconnecting said outlet with said condenser, and means at the entrance ofsaid flue for causing a part of the air current entering said flue tostrike against the inside bottom wall of said'flue thus preventingparticles of lint from collecting on the bottom of the flue.

In a device of the class described, the combination with a cotton seedlinter having an outlet for air carrying lint, of a condenser, a flueconnecting said outlet with said condenser the parts being so arranged.

and proportioned as to cause a part of the air current entering saidflue to move downward against the inside bottom wall of said flue thuspresenting particles of lint from collecting on the bottom of the flue.

8. In a device of the class described, the combination with a cottonseed linter having an outlet for air carrying lint, of means for causingsaid air and lint to reach said outlet whentraveling upwardly at anangle, a condenser, a flue connecting said. outlet with said condenser,the bottom wall of said flue being more nearly horizontal than the lineof travel of the entering air, and means at the entrance of said flue todeflect a portion of said air current down againstthe inside bottom wallof the fine to prevent the collection of lint at that point.

I. In a device of the class described, the combination with a' cottonseed. linter having a. narrow outlet for air carrying lint 8X? tendingacross said linter, of means for causing the air and lint to approachsaid outlet when traveling upward at a considerable angle, a condenser,a flue connecting said outlet with said condenser having side wallsinwardly inclined toward each other and top and bottom walls outwardlyinclined from each other, and means at the entrance of said. flue fordeflecting a portion of said air down against the inside bottom wall ofsaid flue to prevent the collection of lint at that point.

5. In a device of the class described, the combination with a cottonseed linter having a narrow outlet for air carrying lint extendingacross said linter, of means for causing the air and lint to approachsaid outlet when traveling upward at a considerable angle, a condenser,a flue connecting said outlet with said condenser having side wallsinwardly inclined toward each other and top and bottom walls outwardlyinclined from each other, and means at the entrance of said flue for sodeflecting a portion of the entering air as to evenly and uniformlydistribute the lint over the surface of the condenser druni forming auniform-product.

In testimony whereof I al'fi): my signature in presence of twowitnesses.
